WILLIAMUA. MALONEY, on NEEDHAM, MAssAoHusniTs.

Y a citizen of the United States, residing at' DETACHABLE HEEL.

Application led May 24, 1920, Serial No. 383,669. Renewed'Jaiiuary 2.6, V1924.

To all whom t may concer/n:

Be it known that I, VViLLiAM A. MALoNnY,

Newton, in the county of Middlesex and State of Massachusetts, have invented a` newV and useful Detachable Heel, of which the` following is a specification.

This invention relates to a detachable heel preferably of rubber or other resilient material.

Such heels have been heretofore devised to permit the wearer to readily remove and replace a worn heel when desired. It is the object of my invention to provide a construction by means of which a heel may be thus removed and replaced without the use of tools or the manipulation of loose or movable parts. h.

Another object of my invention is to provide a construction in which the inherent resilience of the heel material is, utilized in securing the heel in position on the shoe. V

My invention further relates'to' arrangements and combinations of parts which will be hereinafter described and more p articir larly pointed out in the appended claim.

A preferred form of my invention is shown in the drawings, in which- Fig. 1 is a partial longitudinal sectional elevation of a shoe with my improvements embodied therein;

Fig. 2 is a, bottom View of the permanent part of the heel;

Fig. 3 is a plan View of the detachable heel;

Figs. il and 5 are transverse sectional ele vations of the permanent and Vdetachable parts of the heel respectively; and

Figs. 6 and 7 are pei'spective views of detail parts to be described.

Referring to the drawing, my improved detachable heel comprises a portion 10, permanently secured to the shoe 11 and a detachable portion or heel proper v12, preferably formed of rubber with a .relatively soft lower or tread portion and a relatively hard upper portion. A headed fastening member 13 is preferably formed froinsheet metal bent to the outline shown in Fig. 7and molded or otherwise permanently secured in the -iipper and preferably slightly concave face of the heel 12. The heel 12 is also provided with projections 14 Vand 15, the projections 111 being located near the front corners of the heel and the projection 15 at the rear ofthe heel near the center thereof.

to the shoe and is preferably formed in a general U-shape from a single piece of sheet` metal. The plate 16 is provided with a slot 17 enlarged at one end as clearly shown at 18 in Fig. 6. The plate 16V is preferably secured above-the lower lift of theV permanent heel portion 10, with the slotted por? tion of the plate projecting down into a recess 19 in the heel lift. Elon'gated slots 2() are also provided in this lower lift for the projections 14 and a recess 21 is provided to receive the projection 15. Y

lVhen a heel is to be attached to the shoe, the projections 14 are entered in the rear ends ofthe slots 2O and the head ofthe fastening yfineinber 13 is pushed upward through the enlarged opening 18 at the end of the slot 17. The heel is then pushed forward or longitudinally of the shoe until the head of the member 13 is entered in the 'Y slot 17 of thelock plate 1G. During this operation, tlie rear portion of the heelis bent i position it prevents relative longitudinal.

movement of the heel portions 1() and 12.

The` projections 414 assist inl holding the heel in fixed lateral position on the shoe vand also engage the front ends of the slots Q() to resist force exerted against the rear of the heel in a forward direction as when the heel strikes the ground in walking. TheV lateral and longitudinal strains on the head 13 are thus substantially reduced: j Y The parts are thussecured without the use of tools and it will be also seen that all parts of the device are firmly secured to either the heel or the shoe, there being no loose or movable parts. Vheii the heel becomes worn, it maybe quickly and easily removed vby pulling the rear portion of the heel outward and then pushing Vthe heel rearward, reversing the operation previously described. l

Having thus described my invention, it will be evident that changes and modifications can be made therein by. those skilled in the art within the spirit and scope of my invention as set forth in the claim, and I do not wish .to be otherwise limited to the details herein disclosed, butv what I claim ,is

In a shoe, a heelV comprising a portion permanent-lysecured to the shoe, anda resilihaving a locking plate fixed in position therein, and the other Apart having a headed fastening member formed for locking engagement with said plate, said plate having a slot closely itt'ing said member below the head thereof but enlarged rearward to pei- 10 jections to prevent relative lateral or longitudinal movement of the parte, certain of said recesses being elongatedto permit sliding, locking movement of the detachable heel relatively to the shoe and one of the recesses closely iitting its projection both laterally and longitudinally of the shoe to prevent accidental displacement of the attached heel.

In testimony whereof I have hereunto aii'i'xed my signature.

WILLIAM A. MALONEY.
